Mounting the Device
The
Wireless
HART adapter can be mounted in one of three ways:
■
direct connection to the field device,
■
separate from the field device, but connected by a cable,
■
when used as a repeater, as an autark unit.
Direct connection
The direct connection to a field device is made by means of an adapter piece which is screwed
into the cable entry at the side of the adapter. See chapter 3.2.1

Danger!
Explosion hazard
If the cable glands are not fitted correctly, the IP degree of protection cannot be ensured and
the electronic components can be exposed to an explosive atmosphere.
Check cable glands:
■
all screws of the housing / housing cover must be tightened with the appropriate torque
■
only cables of the appropriate size must be used in the cable glands
■
all cable glands must be tightened with the appropriate torque
■
all seals must be undamaged and fitted correctly
■
all empty cable glands must be sealed with appropriate plugs
